birthday gift

[TexasAGD]

I need everyone's help and input. My boyfriends' birthday is comming up next month. I was thinking about making him and his 3 fraternity little brothers shirts so that they can all be linked together. I am making shirts for his little brothers too because he has been nothing but a good big brother and they look to him for everything. I want them to have something since my boyfriend will be graduating this semester. Now, all I need is an idea for the design. I have made many shirts in the past, but they were all for girls. The shirts I plan on using are those baseball jerseys with white down the chest area with some color, maybe blue, down the arms between the wrist and the elbow. I hope you know what I am talking about. I was thinking about putting their letters in the front with the number 1 for best big brother and something written on the back that ties them and brotherhood together, maybe their names and a slogan. so, if you guys can help me out it would be very much appreciated. a design and slogan idea would be great. Thanks!
